Upload the mailchimp-for-rtb.zip file which you downloaded with your purchase.

Once installed, click the Activate Now link. If you don’t see that link, you can go to your Plugins list at any time and activate it from there.

Activate your license key

Once you’ve installed and activated the plugin, you should activate your license, which entitles you to support and updates for one year.

Go to the Bookings > MailChimp License page in your WordPress admin area. Enter the License Key which was provided in your purchase receipt and click the Save Changes button. When the page reloads, you’ll see a button to Activate License.

If you’re adding this to a development site, remember to deactivate the license before moving the site to a live URL, then reactivate it on the live site.
